Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

In this activity, multiple learners will use a game with ballloons to learn about coqui frog behavior.

In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

Why should we wear masks? Do masks work? Do some masks work better than others? Learners find out in this activity.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.
